Stereo Image Compositing for 3D Object Depth and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to properly synthesize three-dimensional objects into stereo images, resulting in two-dimensional display of the objects when integrated into stereo images.
Innovation Solution
An image synthesizing apparatus that includes a storage unit, an accepting unit, an arranging unit, a generating unit, and an output unit, which arranges three-dimensional objects in a three-dimensional virtual space such that the points of sight for the right and left eyes intersect, generating a second stereo image that avoids the three-dimensional object being located on the back side of the first stereo image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single two-dimensional image generated by 3DCG is synthesized into each of an image for the right eye and an image for the left eye contained in a stereo image, then the three-dimensional object can be integrated into the stereo image, but the three-dimensional object is two-dimensionally displayed and loses its three-dimensional appearance
Solution Approach 1:
The patent applies dimensionality change by arranging the right-eye and left-eye images in a three-dimensional virtual space with specific depth positioning, rather than simply compositing 2D images. The images are positioned at different depths along the optical axis, creating a three-dimensional structure that preserves the spatial relationship and enables proper three-dimensional display of objects within the stereo image.
2Adaptability or versatility
If the first image for the right eye and the first image for the left eye are arranged in the three-dimensional virtual space, then the three-dimensional object can be positioned in space, but the object may be located on the back side of the stereo image and become invisible
Solution Approach 1:
The patent applies preliminary anti-action by pre-positioning the right-eye and left-eye images at appropriate depths in the three-dimensional virtual space before compositing the three-dimensional object. This preliminary arrangement ensures that the object will be visible and not occluded by the stereo images, preventing the visibility problem before it occurs.
3Ease of manufacture
If the stereo image is synthesized using conventional methods, then the processing is simple, but the synthesis is improper and the object appears two-dimensional
Solution Approach 1:
The patent introduces a three-dimensional virtual space as an intermediary environment for arranging and compositing the stereo images and three-dimensional objects. This intermediary space provides a structured framework that maintains spatial relationships and enables accurate three-dimensional synthesis, while the overall process remains computationally efficient through automated rendering.

AI summary
An image synthesizing apparatus stores a first stereo image having a first image for the right eye and a first image for the left eye, arranges a three-dimensional object in a three-dimensional virtual space, generates a second stereo image containing a second image for the right eye, which is an image from the point of sight for the right eye in a state in which the first image for the right eye is displayed, and a second image for the left eye, which is an image from the point of sight for the left eye in a state in which the first image for the left eye is displayed, in the three-dimensional virtual space in which the three-dimensional object is arranged, and outputs the second stereo image.
